Yep fresh poured bullets will check softer than the ingots !
Give em a couple days to check em then again in a couple weeks & see what happens !
Your alloy seems to contain enuff alloys for the 40 (the scale is`nt as accurate with pistol bullets) & I usually use an alloy of 10bhn for all but the highest pressure revolver & rfle loads .
If the bullets fits the chamber & bore the softer alloys will usually withstand alot before leading ,but once that limit is reached it`ll all go south fast !!!!
The name of the game is to keep the pressure behind the bullet!!!
